Monster Christmas — Lewis Trondheim

Peter and Jean, two mischievous kids, love to draw monsters. They create Oko, a frightening monster which escapes from the sheet of paper and disappears into their house. All they need do now is create a nice monster that eats bad ones. That's how Chris, with three legs, four arms and ten mouths, becomes the family's new pet monster. For Christmas, Jean & Peter go on vacation to the mountains with their parents. Chris was supposed to stay at home but he manages to make the trip on the roof of the car. Suddenly an avalanche blocks the road, caused by a monster in hot pursuit of… Santa Claus! It's up to the kids and their pet monster to save Santa and Christmas! But it looks like this monster can have Chris for breakfast!
